Augustus Edward Hough Love predicted the existence of Love waves mathematically in 1911. They form a distinct class, different from other types of seismic waves, such as P-waves and S-waves (both body waves), or Rayleigh waves (another type of surface wave). Love waves travel with a lower velocity than P- or S- waves, but faster than Rayleigh ...
Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. There is a phase difference between these component motions. [1] The existence of Rayleigh waves was predicted in 1885 by Lord Rayleigh, after whom they were named. [2]
Love waves have transverse motion (movement is perpendicular to the direction of travel, like light waves), whereas Rayleigh waves have both longitudinal (movement parallel to the direction of travel, like sound waves) and transverse motion. Seismic waves are studied by seismologists and measured by a seismograph or seismometer.
2. Particle movement perpendicular to wave movement. Rayleigh wave: Surface: 1. Include both longitudinal & transverse motions. 2. Amplitude decreases exponentially with increasing distance from surface. Love wave: Surface: 1. Wave speed lower than P-wave & S-wave, but higher than Rayleigh wave. 2. Horizonal particle movement perpendicular to ...
Seismic tomography or seismotomography is a technique for imaging the subsurface of the Earth using seismic waves. [1] The properties of seismic waves are modified by the material through which they travel. By comparing the differences in seismic waves recorded at different locations, it is possible to create a model of the subsurface structure.
Rayleigh waves travel in a longitudinal manner (the wave motion is parallel to the direction of wave propagation) with particle motion in a retrograde elliptical motion (Figure 1). The Rayleigh waves result from the interaction between P-waves and vertically polarized S-waves. [2] Conversely, Love waves travel in a traverse manner (Figure 1 ...
a P wave in the outer core L: a Love wave sometimes called LT-Wave (Both caps, while an Lt is different) n: a wave that travels along the boundary between the crust and mantle P: a P wave in the mantle p: a P wave ascending to the surface from the focus R: a Rayleigh wave S: an S wave in the mantle s: an S wave ascending to the surface from the ...
S waves may take an hour to reach a point 1000 km away. Both of these are body-waves, that pass directly through the earth's crust. Following the S waves are various kinds of surface-waves – Love waves and Rayleigh waves – that travel only at the earth's surface. Surface waves are smaller for deep earthquakes, which have less interaction ...
